And a display control unit that controls to display an image on the display panel based on an instruction input from the unit.
[0003]
In addition, mobile phones include a foldable mobile phone that is composed of two housings and is compact and convenient to carry so that the two housings can be folded. In a foldable mobile phone, a display panel is arranged inside when two housings are folded, and an operation procedure, a still image, a moving image, and the like are displayed on the display panel. In the following description, when the two housings are folded, the mobile phone may be folded.
[0004]
In addition, some types of foldable mobile phones include a display panel arranged outside the mobile phone when it is folded. In this model, character data such as the phone number, name, and e-mail address of the other party that is usually displayed on the display panel arranged on the outside and that is stored in advance in the memory of the mobile phone Is displayed.
[0005]
The above-described foldable mobile phone in which the display panels are arranged on the inside and the outside usually includes operation means on the inside and the outside, respectively. That is, on the inner side, a key operation unit composed of a plurality of keys used when displaying a desired image on the inner display panel is arranged, and on the outer side, display contents of each character data displayed on the outer display panel The operation keys used when switching between are arranged. When the user presses the key of the key operation unit arranged on the inner side, a desired image is displayed on the inner display panel, and when the user presses the operation key arranged on the outer side, the outer display is displayed. Desired character data is displayed on the panel.
[0006]
Further, in a folding mobile phone, a speaker that outputs a relatively loud sound such as a ring tone for notifying the user of incoming calls and e-mails can receive a ring tone from the user even when the mobile phone is folded. The mobile phone is arranged so as to be located outside when the mobile phone is folded.
[0007]
Japanese Patent Application Laid-Open No. 2001-186226 discloses an example of a mobile phone. The mobile phone described in the publication is configured such that a main body case and a lid case are connected via a hinge so as to be angularly displaceable, and can be opened and closed by angularly displacing the main body case and the lid case. This is a foldable mobile phone. In this cellular phone, a key operation unit is arranged on the main body case so that the cellular phone is inside when the cellular phone is folded. The lid case incorporates one liquid crystal display device, and the lid case is formed with an inner display surface and an outer display surface at positions facing both surfaces of the liquid crystal display device. The inner display surface is a display surface that becomes inner when the mobile phone is folded, and the outer display surface is a display surface that becomes outer when the mobile phone is folded. Thus, the liquid crystal display device can be viewed from either the inner display surface or the outer display surface. However, since an image is displayed on the inner side and the outer side with one liquid crystal display device, the image display pattern is inverted between the case where the image is displayed on the inner side and the case where the image is displayed on the outer side.
[0008]
This foldable mobile phone is provided with detection means for detecting the folded state of the mobile phone. When the state where the mobile phone is opened is detected by this detecting means, an image display pattern is displayed so as to be discriminated from the inner display surface, and the state where the mobile phone is closed is detected by the detecting means. In such a case, an image display pattern is displayed so that it can be discriminated from the outer display surface.
[0009]
[Problems to be solved by the invention]
In the mobile phone having the above-described two operation means, the same image is displayed on the inner and outer display panels, and two users respectively have the inner key operation unit and the outer portion for the same image as in a game, for example. No function is provided for changing the display content of the image by inputting an instruction regarding the change of the display content of the image from the operation keys. Further, since the mobile phone described in the above publication includes only one liquid crystal display device, the same image cannot be displayed on the inner and outer display surfaces at the same time.
[0010]
In addition, when a user uses a foldable mobile phone to reproduce and view composite data including sound and images such as karaoke data, the images are displayed on a display panel arranged on the inside, The sound is output from a speaker that outputs a relatively loud sound arranged outside. Therefore, the user opens and uses the mobile phone to view the image. In this state, the image display direction by the display panel arranged on the inner side is opposite to the sound output direction by the speaker. Therefore, when viewing the image with the inner display panel on which the image is displayed facing itself, the sound is output in a direction opposite to the direction of the user. Therefore, it becomes difficult for the user to hear the sound and the user feels uncomfortable in the way the sound is heard.
[0011]
Note that a speaker as a transmitter used for a telephone call is disposed on the inner side of the folding mobile phone, and it is also possible to output the sound of composite data from this speaker. However, a speaker as a transmitter is assumed not to be able to output a relatively loud sound because it is assumed that the user directly listens to the sound. In addition, when listening to the sound of the composite data while listening to the speaker as the transmitter, the composite data image displayed on the display panel cannot be viewed.
[0012]
  An object of the present invention is to provide a portable device in which two users can perform a predetermined operation related to image display.TelephoneIs to provide.

[0043]
The mobile phone main body 102 is configured by a relatively flat, substantially rectangular parallelepiped first housing 21 and second housing 22 connected via a hinge 25 so as to be angularly displaceable. That is, the mobile phone body 102 is configured to be foldable by angularly displacing the first housing 21 and the second housing 22. The first display unit 17 is disposed so as to be positioned on the inner side when the two housings 21 and 22 are folded with respect to the first housing 21, and the second display unit 19 is disposed with respect to the first housing 21. The two casings 21 and 22 are arranged so as to be positioned on the outer side when folded. The first and second display units 17 and 19 are arranged so that the image display directions are opposite to each other.
[0044]
The “display direction” refers to the direction in which the image is best seen when the image is displayed on the display units 17 and 19, that is, the direction with the best visibility. In the present embodiment, when a liquid crystal display is used as the first and second display units 17 and 19, an image displayed on the display surface of the liquid crystal display is visually observed if it is within a predetermined viewing angle range. Can do. Therefore, in the case of a liquid crystal display, a direction perpendicular to the display surface, which is a direction with particularly good visibility, in the visible range is defined as a “display direction”.
[0045]
The key operation unit 9 is disposed on the inner side when the two casings 21 and 22 are folded with respect to the second casing 22. The second housing 22 is provided with an input jack 24 on the left side in FIG. 2A (the right side in FIG. 2B). As shown in FIG. 2B, the connection jack 23 of the connection cord 23 is inserted into the input jack 24 when connecting the mobile phone body 102 and the external operation unit 101.

[0046]
In the mobile phone 100, when a user inputs an instruction for displaying an image from the key operation unit 9, the image is displayed on at least one of the first and second display units 17 and 19. When the user inputs an instruction for displaying an image from the external operation unit 101, the image is displayed on at least one of the first and second display units 17 and 19. Therefore, the respective instructions input by operating the key operation unit 9 and the external operation unit 101 by two users are reflected on both display units of the first and second display units 17 and 19, and the key operation unit 9 Images based on instructions input from the external operation unit 101 are displayed on the first and second display units 17 and 19. As a result, when two users input instructions relating to image display from the key operation unit 9 and the external operation unit 101, for example, like a game, the images displayed on the first and second display units 17 and 19 are displayed. The operation of changing the display of can be performed.
[0047]
For example, when a game image is displayed on each of the first and second display units 17 and 19 and one user performs an operation of moving his / her character from the key operation unit 9, the first and second display units are displayed. In the game images displayed on both 17 and 19, a character corresponding to one user can be moved, and when the other user performs an operation of moving his / her character from the external operation unit 101, A character corresponding to the other user can be moved in the game images displayed on both the first and second display units 17 and 19, and a so-called battle game can be performed.
[0048]
Further, as described above, the first and second display units 17 and 19 are arranged so as to be opposite to each other with respect to the first housing 21 and arranged so that the display directions of the images are opposite to each other. The key operation unit 9 is disposed on the first display unit 17 side, and the external operation unit 101 is disposed on the second display unit 19 side. Thereby, for example, when two users input instructions for displaying images on the first and second display units 17 and 19 using the key operation unit 9 and the external operation unit 101, one mobile phone 100 is used. An input operation can be performed in a state where two users face each other across the screen. Therefore, the two users can perform an input operation away from each other as long as the images displayed on the first and second display units 17 and 19 can be viewed to the extent that does not hinder the operation. . Thus, an input operation can be easily performed, and convenience is improved.
[0049]
In addition, the mobile phone 100 can execute by switching between the first mode and the second mode. In the first mode, an image is displayed on the first display unit 17 based on an instruction input from the key operation unit 9, and an image is displayed on the second display unit 19 based on an instruction input from the external operation unit 101. Is displayed. The first mode is a mode that is set when the mobile phone 100 is used as a telephone. In the second mode, an image is displayed on at least one of the first and second display units 17 and 19 based on an instruction input from the key operation unit 9, and based on an instruction input from the external operation unit 101. Thus, an image is displayed on at least one of the first and second display units 17 and 19. The second mode is a mode that is set when a game is played on the mobile phone 100.
[0050]
The mode may be switched automatically by detecting that the external operation unit 101 is connected to the mobile phone body 102, that is, that the connection plug 23a is connected to the input jack 24. You may make it switch by performing predetermined operation using the key operation part 9 and the external operation part 101. FIG. For example, the user selects an item to be displayed and executed on each display unit from a table of contents screen including items such as an electronic phone book, various function settings, and a game, and gives instructions for displaying and executing the selected item. When input is made from the key operation unit 9 and the external operation unit 101, it may be automatically switched according to the selected item, or a switch key for switching the mode is set as the key operation unit 9 and the external operation unit. It may be provided in 101 and switched by the user pressing the switching key.
[0051]
In the first mode, for example, an instruction for displaying an image indicating the current time is input from the key operation unit 9 to the first display unit 17 by the user, and a photograph is displayed on the second display unit 19 from the external operation unit 101. When an instruction for input is input, based on the instructions input from the key operation unit 9 and the external operation unit 101, an image indicating the current time is displayed on the first display unit 17, and the second display unit 19 displays A photo is displayed.
[0052]

For example, when the same image is displayed on the first and second display units 17 and 19 and two users input instructions regarding image display from the key operation unit 9 and the external operation unit 101, the key operation unit 9 and an instruction input from the external operation unit 101 can be performed to change the display of the images displayed on the first and second display units 17 and 19.
[0053]
As described above, the cellular phone 100 has two types of modes, that is, a mode in which an instruction is given to one display unit from one operation unit and a mode in which an instruction is given to two display units from one operation unit, depending on the purpose. Can be used by switching.
[0054]
The external operation unit 101 is configured to be detachable from the mobile phone main body 102. Therefore, when the external operation unit 101 is not used, it can be detached from the mobile phone body 102, and the mobile phone body 102 can be made compact.
[0055]
In the present embodiment, the external operation unit 101 is configured to connect to the mobile phone main body 102 via the connection cord 23, but other connection configurations may be used. For example, the external operation unit 101 may be a cordless operation unit without the connection cord 23. In this case, the mobile phone body 102 and the external operation unit 101 need to include wireless communication means for performing communication with each other. For example, a wireless communication means for performing infrared communication can be used. Position information (data) input from the external operation unit 101 by the user is transmitted to the mobile phone body 102 by infrared communication. The mobile phone main body 102 displays images based on the position information (data) transmitted from the external operation unit 101 on the first and second display units 17 and 19.

[0059]
As a specific example of operations related to image display by two users, for example, in the block breaking game shown in FIG. 4, one of the two users presses the right cursor key of the key operation unit 9 and the other Suppose that the user presses the left cursor key of the external operation unit 101. Here, for the right cursor key and the left cursor key, two horizontal bars B1 and B2 displayed on the first and second display portions 17 and 19 shown in FIG. 4A and FIG. It is assumed that a function for moving a predetermined amount of movement is assigned. When the right cursor key of the key operation unit 9 is pressed by one user, the left of the two horizontal bars B1 and B2 displayed in parallel in the horizontal direction on the first and second display units 17 and 19 The horizontal bar B1 located at the position moves by a fixed amount of movement to the right in the horizontal direction. When the other user presses the left cursor key of the external operation unit 101, the horizontal bar B2 located on the right side of the two horizontal bars B1 and B2 moves to the left in the horizontal direction by a fixed amount of movement. Images obtained when the above-described operation is performed are displayed on both the first and second display units 17 and 19.
[0060]
Therefore, the respective instructions input by operating the key operation unit 9 and the external operation unit 101 by two users are reflected on both display units of the first and second display units 17 and 19, and the key operation unit 9 Images based on instructions input from the external operation unit 101 are displayed on the first and second display units 17 and 19. As a result, two users can change the display of the images displayed on the first and second display units 17 and 19 by inputting instructions related to image display from the key operation unit 9 and the external operation unit 101. It can be carried out.
[0061]
FIG. 5 is a flowchart illustrating an example of a control process when two users play a game using the mobile phone 100. In step S1, a communication mode (first mode) in which radio communication is performed with a base station via radio waves is shifted to a game mode (second mode) in which two users play a game, and the game is started. In step S2, it is determined whether or not a key of at least one of the key operation unit 9 and the external operation unit 101 has been pressed. If it is determined in step S2 that a key of at least one of the key operation unit 9 and the external operation unit 101 has been pressed, the process proceeds to step S3.
[0062]
If it is determined in step S2 that the keys of the key operation unit 9 and the external operation unit 101 are not pressed, the process proceeds to step S12. In step S12, the key operation unit 9 and the external operation unit 101 are in a key standby state. In the standby state, a process for executing the game program is performed. For example, in the case of the block breaking game shown in FIG. 4, processes other than the interrupt process such as a process of displaying blocks and balls on the first and second display units 17 and 19 and a process of moving the balls are performed.
[0063]
In step S <b> 3, an interrupt is generated by pressing a key on the key operation unit 9 and the external operation unit 101. In step S4, the first and second key matrices 10 and 11 detect position information indicating which position of the key operation unit 9 and the external operation unit 101 is pressed, and transmit the detected position information to the CPU 13. To do. For example, in the block breaking game shown in FIG. 4, it is assumed that one of two users presses the right cursor key of the key operation unit 9 and the other user presses the left cursor key of the external operation unit 101. . At this time, the first and second key matrices 10 and 11 detect that the right cursor key of the key operation unit 9 and the left cursor key of the external operation unit 101 are pressed, and the interrupt controller 12 is pressed as a detection result. An interrupt request signal including the position information of each key is transmitted to the CPU 13.
[0064]
In step S5, it is determined whether or not an end key for ending the game mode has been pressed. If it is determined in step S5 that the end key has been pressed, the process proceeds to step S13. In step S13, the game is ended and the game mode is shifted to the communication mode. If it is determined in step S5 that a key other than the end key has been pressed, the process proceeds to step S6.
[0065]
In step S6, an interrupt process is started. In this embodiment, an image is displayed on the first and second display units 17 and 19 in accordance with the instruction pressed and input in step S2, and a process of outputting an operation sound is started. Here, in step S4, processing pre-assigned to the right cursor key of the key operation unit 9 and the left cursor key of the external operation unit 101 pressed by two users is performed. For the right cursor key and the left cursor key, for example, two horizontal bars B1 and B2 displayed on the first and second display portions 17 and 19 shown in FIGS. 4A and 4B are determined in advance. It is assumed that a function for moving the movement amount is assigned. When the right cursor key of the key operation unit 9 is pressed by one user, the left of the two horizontal bars B1 and B2 displayed in parallel in the horizontal direction on the first and second display units 17 and 19 The horizontal bar B1 positioned at is moved to the right in the horizontal direction by a fixed amount of movement. When the other user presses the left cursor key of the external operation unit 101, the horizontal bar B2 located on the right side of the two horizontal bars B1 and B2 is moved to the left in the horizontal direction by a fixed amount of movement. Images obtained when the above-described operation is performed are displayed on both the first and second display units 17 and 19. When the right cursor key and the left cursor key are pressed, an operation sound is output from the speaker 8.
[0066]
In this way, when the same image is displayed on the first and second display units 17 and 19 and two users input instructions related to image display from the key operation unit 9 and the external operation unit 101, the key operation is performed. Based on the instructions input from the unit 9 and the external operation unit 101, an operation for changing the display of the images displayed on the first and second display units 17 and 19 can be performed.
[0067]
  Next, in step S7, it is determined whether or not a new interrupt has occurred during the interrupt process. If it is determined in step S7 that a new interrupt has occurred during the interrupt process, the process proceeds to step S8. In step S8The secondThe first and second key matrices 10 and 11 detect position information indicating which position of the key operation unit 9 and the external operation unit 101 is pressed, and the detected position information isBy the interrupt controller 12,The data is stored in an internal memory in the CPU 13. When a plurality of keys of the key operation unit 9 and the external operation unit 101 are pressed at the same time and a plurality of interrupts are generated,The interrupt controller 12Based on predetermined priority, Position information of each key in order of priorityIs stored in the internal memory in the CPU 13.
[0068]
If it is determined in step S7 that no new interrupt has occurred during the interrupt process, the process proceeds to step S9. In step S9, the interrupt process assigned to the pressed key is terminated. Next, in step S10, it is determined whether an interrupt is stored in the internal memory in the CPU 13. If it is determined in step S10 that an interrupt is stored in the internal memory in the CPU 13, the process proceeds to step S11. In step S11, interrupt processing is performed based on the interrupt order stored in the internal memory of the CPU 13 and the position information of the pressed key. Next, returning to step S7, it is determined again whether or not a new interrupt has occurred during the interrupt processing in step S11. In step S7, when a new interrupt occurs during the interrupt process, the process of step S8 is performed again. The processing from step S7 to step S11 is repeated until there is no interrupt stored in the internal memory in the CPU 13 in this way.
[0069]
If it is determined in step S10 that no interrupt is stored in the internal memory in the CPU 13, the process proceeds to step S12. In step S12, the key operation unit 9 and the external operation unit 101 are in a key standby state. If the key of the key operation unit 9 and the external operation unit 101 is newly pressed by the user in the key standby state in step S12, the processing after step S2 is performed.
